IPC: C25D5/54
Filed: 1981-06-24
Abstract: PURPOSE:To uniform thickness of plating, and to improve adhesiveness owing to improvement of wetness, by baking a carbon fiber bundle or its cloth consisting of carbon single fibers on which a bundling agent is applied, in an oxidation atmosphere, before plating. CONSTITUTION:A carbon formed substance, especially, a carbon fiber bundle or its cloth consisting of single fibers on which a suitable bundling agent is applied in advance is subjected to a burning treatment in the air or an oxidation atmosphere. As a result, a bundling degree or a coupling degree of the carbon single fibers is raised, therefore, the applied bundling agent or coupling agent is decomposed, and subsequently, when the carbon fiber itself is oxidized, roughing and activation of the surface of the single fibers are caused. As a result, equalization of metallic plating and a rapid improvement of adhesiveness can be attained. In this regard, the baking treatment conditions are very important, and especially, excessive baking exerts influence on a characteristic of the carbon fiber itself, mechanical strength of the fiber bundle or cloth is remarkably dropped, and both plating work and post-treatment work are remarkably deteriorated.

Abstract: PURPOSE:To suppress the vibration of a moving unit at the time of its positioning and reduce a position setting time by a method wherein four state values composed of predetermined estimated values are estimated by calculation by the same dimensional observer in a control system and the integrated value of an angle deviation is corrected by feedback in accordance with the results of the calculated estimation.

A corrected speed target value V(i)* is determined as a target speed for a speed feedback loop. As the target speed is corrected by feedback of the distortion angle alpha(i) ad the distortion angular velocity beta(i), the torque of a servo motor can be so controlled as to reduce the deviation of the integrated value of the angle deviation from the distortion angle alpha(i) and the distortion angular velocity beta(i).
